express

问题 I have an ordinary var express = require('express') Node express www page, using session, pug, etc as usual. My db calls var db = require('./scripts/myHappyMysqlScript') I'm naturally using mysql , so in the db script var mysql = require('mysql') So for example app.get('/catPhotos', (req, response) => { response.render('catPhotos.pug'); }) Say a page has a table showing something from the petNames database, app.get('/pets', function(req, res, next) { db.allPetNames(function(err, petsList) {

问题 I'm trying to make a simple server with node, express and ejs for the template. I've gotten the server to point to the page, load it, and am even able to generate other bits of code with the include statement. However for some reason the style sheet will not load. app.js var express = require('express'), app = express(), http = require('http'), server = http.createServer(app), fs = require('fs'); var PORT = 8080; app.set('view engine', 'ejs'); app.get('/', function(req, res){ res.render(

问题 From what I read, there are a couple of ways to run java files in a node.js application. One way is to spawn a child process: (the java code is packaged with dependencies in an executable jar .) var exec = require('child_process').exec, child; child = exec('java -jar file.jar arg1 arg2', function (error, stdout, stderr){ console.log('stdout: ' + stdout); console.log('stderr: ' + stderr); if(error !== null){ console.log('exec error: ' + error); } }); The other way is to use the java - npm

问题 Pg-promise is Not returning anything for 60s and gets timed out while running server setup with express-generator. There are no error messages. All the routes without db.any or similar query, works fine. The routes with db.* times out. But, the same connection/route/query works perfectly with a simple express app. I am running this from AWS EC2. Here is the test sample express that worked fine. Same route in routes/index.js does not work - gets timed out. const express = require('express');

问题 As the title suggests, I am getting error: {"message": "ENOENT: no such file or directory, open 'E:\\astrology\\utils\\uploads\\1600798534862qf.png'"} in my project even after passing every required configs. Note: I've divided 'app' into two parts: main 'app.js' and 'appRoute.js' for more dynamic and code clarity. app.js const express = require("express"); const path = require("path"); const app = express(); const directory = path.join(__dirname, "utils/uploads"); app.use("/uploads", express
